Abstract

Prasanna Latha* D and K.P.J. Hema Latha

In vitro antibacterial and antifungal activity of the chloroform extracts of the green macroalgae, Enteromorpha compressa and Chaetomorpha antennina at different concentrations were screened against two gram positive bacteria, Staphylococcus aureus, Bacillus subtills, two gram negative bacteria Escherichia coli, Proteus vulgaris and two fungal species Aspergillus niger, Candida albicans by cup plate method. The extracts were found to inhibit the growth of all the bacteria and fungal organisms tested. The antimicrobial effect of extracts were comparable with the standard antibacterial agent, benzyl penicillin and fluconazole as standard antifungal agent and were found to be active against all the organisms tested.
